The invention is illustrated as applied in the forming of a jointbetween a spout or nozzle A and a container wall member, for example ametallic can end B. The nozzle A is shown as being conventionallythreaded at I for receiving a screw cap, but it may insteadbe formed ining a diierent kind of closure such as a stopper :bye a-iseam lforming`part generally designated Il.. The-.apart uit," which-is immediatelyadjacentkthe aperturewilzmcompriees.enbase portion `I;2*and a sea'ming'hook.rltsbentout:ofwthe plane 1oi the base I2 so as to extendupwardlyvasviewedin Figure 3;.11 i'. Mw r w v fwonxordemtoIassemble thepartsl A landl B, the camend iisfiplaced with its `base fportion I2resting on a support I4 as shown in Figure 5. The

ynozzle A is placed over the can end B in axial alignment with theaperture I0, the relative positions of the parts A and B then being asshown in Figure 4. Preferably the nozzle A is supported by a member I4which extends under the attaching end 5 and up into the body 3 of thenozzle as shown in Figure 5.

u With the parts positioned in this way, the edge portion I3 of the canend seam forming part II will engage the intermediate inclined portion 6of the nozzle seam forming part 4. A die I5 is then moveddownwardly sothat the flat lower die surface I6 presses on the intermediateseamportion 6 at iirst only at its periphery, that is adjacent thereturn bend 8, las shown in Figure 5. Pressing movement of the die I5 iscontinued while the base portion I2 is supported on the member I4. Theintermediate seam forming portion 6 is bent downwardly which causes thecan end edge portion I3 to be cammed and bent outwardly and downwardlyso as to extend between the nozzle inclined seam portion 6 and thereturn bent edge portion 9. During the last part of the pressingmovement the surface I6` of the die I5 will engage and press on the seamprovidea seaming hookf which; 'is n forming portion 6 over the majorportion of its area so as finally to compress the intermediate seamforming portion 6, the return bent edge portion 9, and the wall memberedge portion I3 all into parallelism with the base portion I2.

Preferably the die I5 is formed With a rib I1 which, during the lastphaseof the pressing operation, pushes a small `.ring oftlie"nozzlefseam forming portion 4 downwardly to provide a" locking beadI8 for preventing lateral shifting or sliding of the parts A and Brelative to each other.

It will be observed that this method of assembling the nozzle or spout Aand the can end B y ing from the invention as defined in the claim.

enables a strong tight joint to be formedv with y a single pressingoperation' and without its being necessary to use intermediate dies andto trans- I claim:

The combination of a container end having a flange at its outerperipheral portion and a central opening, the metal of the end beingshaped so as to extend downwardly and inwardly from the flange, thenceinwardly and thence up- ,j wadly to surround said central opening,theporl tionv of the end surrounding the opening being 10' "having avertically disposed body portion probent outwardly to form a seaminghook, a nozzle vided with a dispensing opening at the upper end thereof,said body portion of the nozzle having at its lower end thereof anoutwardly extending portion overlyingv the seaming hook on the containerend and bent back upon itself to form a i seaming hook which extendsinto and interlocks fer the work to other dies aftert the partszhavebeen only partially assembled.

In the completed assembly, the spout'or nozzle A projects outwardly(upwardly as viewed in Figure 1) from the outsidey(upper)svurface"offthe can end B. Consequentlyv the nozzle is subjectvvto being struck or pushed, Yas when cans are' packed or piled on oneanother, tending to push the nozzles from the outside towards the insideof the can end.` Becausefof the novel joint'be- -tween the nozzle A andcan end B suchpressure pushing the nozzle A' toward the can causestlieintermediate portion 6 of the nozzle intermediate seam forming part topush against the underlyi ing joint forming portions I3, 9,and'fl2,thereby compressing these parts togetherand tightening thejointrather than opening it.`

In the completed assembly the seeming hook 9 of the nozzle interlockswith the `seaming hook I3 on the can end. The metal of the nozzle inthel region I8 is bent downwardly around `thebase of the seaming hook`I3 and the inclined wall ofk the can end extends upwardly and bearsagainst with the seaming hook on the container end, said inclinedportion on the end adapted to extend the base of the seaming'hook'S.This will'hold f4() the interlocked hooks in tight engagement'which i isnot in anyway disturbedby the springing' of the metal partsfintheregions adjacent thei'n'- terlocked hooks. In fact, downward pressureon the nozzle as notedV above; `tighte'nsy the joint rather than loosens`the same. f-

The method and assembly disclosed by of Y example are preferred,but'itWill bey 'apparent' that changes could be resorted towithout`depart' around a portion of the base of the seaming hook -on thenozzle andssaid outwardly extending portion of thenozzle being bentdownwardly and .tightly around the ybase ofthe seaming hook vformed onthe container end so that downward Ipressurefon .the nozzle will tend todraw the inclined portion of the end around the base of the nozzleseaming hook and alsodraw th'e outwardly extending portion of the nozzlearoundfthe base of the seaming hook on the container endl and therebytighten the same; l
